CORN-HARROW.

SPECIFICATION forming part of Letters Patent No. 270,241, dated January9, 1883. Application filed August 28,1882. (No model.)

To all whom it may concern Be it known that I, SAMUEL Y. MILLER,residing in Union county, Indiana, 'near Gontreras, Butler county, Ohio,haveiuventcd certain new and useful Improvements in Corn- Harrows, ofwhich the following is a specification, and the accompanying drawing aperspective View.

This invention relates to barrows for operating at once upon both sidesot a corn-row, as hereinafter specified.

The device is to be used in connection with a wheeled frame or sulky,such as is commonly used in connection with sulky plows and cultivators.

In the, drawing, common sulky used for plows, 850. This axle may bestraight, as shown, or it may be arched to pass overghigher corn.

B B are parallel beams freely attached to the axle A, so as to oscillatevertically and horizontally, and projecting rearward; G C, handlesattached to the beams; D D, harrowframes below the rearends of thebeams; E, barrow-teeth; 1*, a share-tooth atinner rear extremityot'harrow-irame; Gr,iI0Il tooth-seats, located against the sides of thebarrow-frame; H, 'eyebolts to receive the tooth-shank and clamp thetooth and tooth-seat against theharrow-t'rame; I, the shanks of theteeth; K, a snspension-bar from beam to prow of barrow-t'rame; L, theattaching point of suspension-bar K to beam, being a pivot-bolt with twoor more holes provided for it, so as to admit of vertical adjustment ofthe suspended harrow-frame; M, a diagonal draft-rod from beam to a pointnear the bottomof the suspension-rod K; O, a break-pin atjuncture ot'draft-rod M and suspension-rod K; P, a hookand-eye connection betweenbottom of suspension-rod K and barrow-frame; Q, a rear suspension-rod,pivoted to beam at It, in a manner similar to L, and attached to theharrowframe at S, the same as the suspension-rod K is attached at P; T,a metal arch-bar, journaled at U to the barrow-frame; V, a clamp forbinding the rear suspension-rod, Q, to the A represents the axle of aarch T when desired; W, the inner rear extremity of the barrow-frame,and W the outer rear extremity of the barrow-frame. \Vhile only one ofthe barrow-frames is shown as provided with teeth, it is to beunderstood that both frames are similarly provided.

In operation the double barrow D D dies the corn-row, W, running closeto the growing corn. The share-teeth I thus running close to the corn,throw the soil away from the corn and leave the corn upon aslightly-elevated ridge. Only certain conditions of crops and soilrender this necessary, and the share-teet h 1*, having shanks like theharrowteeth E, may be removed and barrow-teeth put in their place. Insome cases it may be desirable to put barrow-teeth at W in place ofshareteeth I and to put the shareteeth in the next forward position,which brings them farther from the corn and gives a harrow-tooth closeto the. corn. The two harrowframes D D, being hung freely at points Sand P, are at liberty, when clamp V is loosened, to he self-adjusting tosuit the slope of the land each way from thecorn-row. The arches Tpermit the two barrow-frames to be adjusted to suit a certain slope, andto be firmly clamped in the proper position. The suspension-rods K and Qbeing adjustable in length, by altering the pivot positions at L and Itpermits stradeither the front or rear of the harrow-frames to beadjusted to work at a greater or less depth with reference to the radialposition of the beams B. The form of tooth-hold'erGgives a substantialmeans for attaching and detaching the teeth.

Instead of the triangular form of harrowframe shown, any of thewell-known shapes may be employed.

1 claim as my invention- The combination,substantially as set forth, ofaxle A, beams B, barrows D, suspensionrods K and Q, arches T, and clampsV.
